CPT code 69602 represents a surgical revision converting a prior simple or complete mastoidectomy into a modified radical mastoidectomy. It is used when a previous mastoidectomy fails to achieve a dry ear, leading to recurrent otitis media with purulence, eardrum perforation, and persistent or recurrent hearing loss. The code captures a definitive operative intervention aimed at removing residual infected mastoid air cells and granulation tissue and reconstructing the ear canal when necessary.

This publication addresses national implications for otologic surgery coding and payment. Key payers covered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context for when the code is applicable, typical sites of service, and the procedural elements that define the service. The report outlines billing considerations and common modifiers (input provided), and highlights areas where documentation should support the revision nature of the procedure and failure of prior mastoidectomy.

Intended for clinicians, billing professionals, and policy analysts, the summary provides benchmarks and policy-relevant insights into coding use and payer coverage patterns. Data not available in the input for some comparative benchmarks and associated taxonomies is noted.
